PATENT OFFICE. I

EXCAVATOR.

SPECIFICATION forming part of Letters Patent No. 322,319, dated July 14,1885.

Application filed J' une 9, 1884. (No model.) I f y To all whom it mayconcern:

Beit known that'we, BENJAMIN K. REED and BAETLEY L. BUREIs, of Wichita,in the county of Sedgwick and State ofKansas, have invented a new anduseful Improvement in Excavators; and we do hereby declare that thefollowing is a full, clear, and exact description of the same.

Our invention relates to excavators of that class in which the earth iscarried up and discharged by means of endless belts or conveyers.

In the accompanying drawings, Figure l is a side elevation, and Fig. 2is a plan view, of the apparatus. Fig. 3 is a transverse section throughthe carrying-wheels. Fig. 4 shows in detail the mechanism for drivingthe transverse conveyer.

A main frame, A, is supported on wheels b b and B B', and carries theworking parts. The wheelsB B are. loose on an axle,C, and each has acircular rack, c, interval teeth. On the frame is journaled a shaft, d,with a pinion, 7, meshing into the internal gear of wheel B. A largerpinion, D, on the same shaft meshes with a pinion, E, on countershaft e.The timbers F Fof the frame on which the shafts d and c are journaledrun longitudinally, and one is by the side of the opening left for themain elevator. On the shaft e is a sprocket-wheel, G,connected by achain, f, to asprocket-wheel, g, cn the shaft of the upper roller of themain elevator. This elevator may, therefore, be adjusted by raising orlowering its upper end without deranging the gearing.

The internal gear on wheel B is in mesh with a pinion, II,-on shaft 7i,journaled in a short beam, K, the forward end of which is supported onthe axle. On the inner end of the shaft 71, is a bevelgear, 7c, in meshwith a little gear, Z, on a shaft, L, journaled in the frame. On theouter end of this is a sprocket-wheel, L', which is connected by a chainto a like wheel,`Z, on the end of the roller-shaft of the lateralconveyer or elevanates just over the front end of the main conve er.byystandards p g and cutter'fr, both of thin iron. The beam is connectedat the rear end to the frame by links l and 2, so that it may swingfreely in vertical plane. The front vend is connected to the pivoteddraw bar or The plow is connected to the beam link, which has a verticalconveyer-arm, Q,

on the rear end. This link is pivoted in a hanger, t, on the frame, andthe arm Q Is provided with rack-teeth, into which meshes a segment, 3,pivoted between two plates or standards, 4 4, on the frame. The armQalso passes between these standards, and is thus held constantly ingear with the segment. A

spring handle or lever, 5, fixed to the segment, moves past andengageswith a curved rack, 6, by means of which the plow can he.

set at any desired depth, and by reason of the manner of suspending theplow always maintains approximately the saine level.

The forward wheels are mounted on a short axle, with ordinary fifthwheel connectionwith the frame. to turn by the side of theplow-connections The axle allows thefwheelj quite around to right orleft, and the whole l machine may thus be turned in very small space.The plow cutsbehind these wheels,

and the low and slightly-inclined mold-board` conveys the earth back tothe conveyers,which are of ordinary construction, and carry the 1 earthup and discharge it in the usual manner. A

As the wheels are independent, and one i connected to the main and theother to the lateral conveyer, they may turn in opposite tached to apivoted draw-bar provided with rack-arms and segment, the n1old-boardextending back-to and connectedwith the main elevator, substantially asdescribed.

In testimony whereof we have signed our l names to this specification inthe presence of two subscribing witnesses. BENJAMIN K. REED.

BARTLEY L. BURRIS.
